The need of accurately reproducing the behaviour of elastoplastic materials in
computational environments for the solution of engineering problems motivates the …

When using an implicit numerical integration algorithm to implement a highly nonlinear
elasto-plastic constitutive models in FEM simulations, some difficulties would encounter …

As inelastic structures are ubiquitous in many engineering fields, a central task in
computational mechanics is to develop accurate, robust and efficient tools for their analysis …

A mixed membrane eight‐node quadrilateral finite element for the analysis of masonry walls
is presented. Assuming that a nonlinear and history‐dependent 2D stress‐strain constitutive …

Nonlinear FEM analysis for beamsand plate assemblages basedon the implicit corotational
method Page 1 Journal of Mechanics of Materials and Structures NONLINEAR FEM ANALYSIS …

A novel high-performance eight-node quadrilateral mixed finite element is presented. Its
formulation is based on a Hu-Washizu type functional, suitable to the treatment of material …

We investigate the use of a second-order cone programming (SOCP) framework for
computing complex 3D steel assemblies in the context of elastoplasticity and limit analysis …

This work makes the Minkowski sum of ellipsoids into a consolidated tool for the
representation of the yield surface of arbitrarily shaped composite cross sections under axial …

Damage, cracking, and strain localization mechanisms often lead to unstable structural
responses characterized by snap-backs (ie, force and displacement decrease …

The paper proposes a 3D mixed finite element and tests its performance in elasto-plastic
and limit analysis problems. A composite tetrahedron mesh is assumed over the domain …
